无法在我的乳胶代码中发现错误

你好，LaTeX 社区，

我正在制作一个模板，几乎要完成了，但我的代码中有一个故障，我无法找到它。在渲染代码时，无法\textbf{Question \questionnumber:} \questiontext 正确渲染。\questionnumber输出中未显示。

当前输出：Question : 期望输出：Question 1 :

注意：我是 LaTeX 和这个社区的新手，如果您有任何建议或与我当前方法不同的方法/想法，请随时评论您的想法和想法，这将有助于我提高代码质量。

答案1

问题是您在使用时提供的第一个键前面添加了两个空格。第一个是由 的错误定义添加的\mcqimgsideFourOne，第二个是由它的使用添加的。使用时的空格不应该是一个问题，如果定义正确，它也不会是一个问题。但是xkeyval（与大多数其他 key=value 解析器一样）只会从键或值的两端删除一个空格。因此会搜索␣questionnumber未定义的。

如果你修复了你的定义，你的使用就会有效（请注意，这个答案只能修复错误，并不能改善其他任何东西）：
